在PHP中更快地处理多个cURL请求 [英] Proccessing Multiple cURL requests in PHP faster

问题描述

我正在尝试通过有效处理cURL请求来加快我的网站的速度。我正在运行大约3个请求，其中两个转到同一服务器。这是我的代码：

I am trying to speed up my website by processing the cURL requests efficiently. I am running about 3 requests, two go to the same server. Here is my code:

$profile = curl_init();
curl_setopt($profile, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($profile, CURLOPT_RETURNTRANSFER, true);
curl_setopt($profile, CURLOPT_FAILONERROR, true);
curl_setopt($profile, CURLOPT_URL,"https://owapi.net/api/v2/u/".$battletag."/stats/".$mode."?platform=".$platform);
$result = curl_exec($profile); //grab API data
curl_close($profile);
$stats = json_decode($result, true); //decode JSON data


$profile1 = curl_init();
curl_setopt($profile1, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($profile1, CURLOPT_RETURNTRANSFER, true);
curl_setopt($profile1, CURLOPT_FAILONERROR, true);
curl_setopt($profile1, CURLOPT_URL,"https://api.lootbox.eu/".$platform."/us/".$battletag."/profile");
$result1 = curl_exec($profile1); //grab API data
curl_close($profile1);
$stats1 = json_decode($result1, true); 

$hero_stats = curl_init();
curl_setopt($hero_stats, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($hero_stats, CURLOPT_RETURNTRANSFER, true);
curl_setopt($hero_stats, CURLOPT_FAILONERROR, true);
curl_setopt($hero_stats, CURLOPT_URL,"https://api.lootbox.eu/".$platform."/us/".$battletag."/competitive-play/heroes");
$hero_play_time = curl_exec($hero_stats); //grab API data
curl_close($hero_stats);
$heroes_info = json_decode($hero_play_time, true);

如何在不重新启动连接的情况下同时处理这些请求？我想加快网站的加载时间，因为现在需要很长时间。任何帮助，将不胜感激。我听说过curl_multi_init（）方法，但不确定如何正确使用它。

How can I process these requests at the same time without restarting the connection? I want to speed up the load time of my site because right now, it takes a long time. Any help would be appreciated. I have heard of the curl_multi_init() method but I am not sure on how to use it properly. Any help wit that would be welcomed.

谢谢。

好，谢谢大家的帮助。尤其是@Andrew。

Well thanks for all the help guys. Especially @Andrew.

我找到了一个最终奏效的解决方案。

I found a solution that ended up working. Posting it here for other people with a similar problem.

function multiRequest($data, $options = array()) {

  // array of curl handles
  $curly = array();
  // data to be returned
  $result = array();

  // multi handle
  $mh = curl_multi_init();

  // loop through $data and create curl handles
  // then add them to the multi-handle
  foreach ($data as $id => $d) {

    $curly[$id] = curl_init();

    $url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d;
    curl_setopt($curly[$id], CURLOPT_URL,            $url);
    curl_setopt($curly[$id], CURLOPT_HEADER,         0);
    curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1);

    // post?
    if (is_array($d)) {
      if (!empty($d['post'])) {
        curl_setopt($curly[$id], CURLOPT_POST,       1);
        curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']);
      }
    }

    // extra options?
    if (!empty($options)) {
      curl_setopt_array($curly[$id], $options);
    }

    curl_multi_add_handle($mh, $curly[$id]);
  }

  // execute the handles
  $running = null;
  do {
    curl_multi_exec($mh, $running);
  } while($running > 0);


  // get content and remove handles
  foreach($curly as $id => $c) {
    $result[$id] = json_decode(curl_multi_getcontent($c), true);
    curl_multi_remove_handle($mh, $c);
  }

  // all done
  curl_multi_close($mh);

  return $result;
}

$data = array(
  'https://owapi.net/api/v2/u/'.$battletag.'/stats/'.$mode.'?platform='.$platform,
  'https://api.lootbox.eu/'.$platform.'/us/'.$battletag.'/profile',
  'https://api.lootbox.eu/'.$platform.'/us/'.$battletag.'/competitive-play/heroes'
);
$r = multiRequest($data);

此方法有效，我只需要在get_contents方法上添加json_decode方法即可。

This worked, I just had to add the json_decode method over the get_contents method.

再次感谢大家。非常感谢您的帮助。

Thanks again everyone. Really appreciate the help.
